Entourage star Jeremy Piven has been slammed by his ex-girlfriend Kate Nardi after the blonde labelled him a ‘worst guy’ she's been intimate with.

Speaking out about her time with the Mr Selfridge star in a new interview, the busty beauty told The Sun that she was left unimpressed by his skills in the bedroom and claimed it was like ‘having sex with a librarian.’

The 27-year-old model explained: ‘We had sex but he is the worst guy I’ve slept with. He didn’t say anything, just the occasional grunt.’
